"He's a good bowler and a good competitor," Kane Williamson said yesterday.
"They tend to bowl quite straight and are pretty accurate. They can wear you down.
"As a spin unit we've been looking to bowl quicker with the nature of these surfaces. If you're bowling slow the ball sits in the wicket and makes it easier [for batsmen]."
The part time offspinner, whose role has assumed more significance this year, feels it can be harder to face spinners in Bangladesh conditions who deliver the ball faster through the air.
Coach Mike Hesson has spoken of senior spinner Bruce Martin's need to change his approach and bowl with more pace.
The team for the test had not been named last night and Williamson wasn't giving any secrets away. However, the batting is unlikely to change and the only adjustment would be a third seamer - probably Neil Wagner - for either allrounder Corey Anderson, who made his debut in Chittagong, or one of the two specialist spinners, Ish Sodhi or Martin.
First test century maker Williamson said although pitch and conditions would be factors, so would working out where they are best to attack the Bangladeshis to secure the series win. The days of their hosts being the soft touches of a few years ago are long gone, he believes.
"Without a doubt," Williamson said. "[At home] they're extremely competitive against whoever they play."
That said, they've won just one test out of 40 in Bangladesh.
